Window Company in Avalon, CA
Window and door work on Catalina Island runs on a different clock than the mainland. Every unit, every piece of flashing, every hinge rides a barge or the ferry from the Port of Los Angeles before a crew can touch it. That means planning is everything here, and the salt air off the Pacific punishes standard hardware faster than anywhere else in Southern California. Westlight Windows & Doors handles Avalon jobs with island-specific products and a written price before work starts. Call (903) 354-7134 to talk through your project with a real person.
Why Avalon Homes Are Different
Most of Avalon’s residential stock was built between the 1920s and 1940s: compact Craftsman bungalows and Spanish Colonial Revival cottages on steep hillside lots above the harbor. Wood-framed, single-pane windows from that era have soaked up decades of salt humidity, and the plaster-and-lath walls they sit in have shifted, so openings are rarely square. A replacement window that fits a clean, modern mainland rough opening often needs real carpentry to fit an Avalon wall.
The climate is mild, but the corrosion is not. Onshore spray works its way into tracks, hinges, latch mechanisms, and door thresholds. Standard residential aluminum hardware can fail within a few seasons here. We spec marine-grade coatings and stainless steel components for Avalon because what’s overkill on the mainland is simply baseline on an island 22 miles offshore.
Our Main Avalon Services
The two calls we get most from Avalon homeowners are for replacement windows and for entry or patio doors, with new-construction window installation close behind. Here’s what each involves on the island.
Window Replacement in Avalon
Replacing windows in Avalon means measuring out-of-square openings in older plaster-and-lath walls, then matching the new unit to the home rather than forcing the wall to accept a stock size. Salt-failed tracks and fogged single panes are the usual reasons homeowners call. We carry impact-rated lines like PGT and CGI for west-facing elevations that take direct ocean wind. See the full scope on our Window Replacement in Avalon page.

Window Installation in Avalon
New-construction window installation in Avalon, whether a hillside addition or a full remodel, requires staging every fastener and tube of sealant before the job starts. There’s no supply house run mid-project. We pre-plan the full material list, coordinate barge delivery, and install the unit square in walls that have moved over eight or nine decades. Details are on the Window Installation in Avalon page.

Door Installation in Avalon
Entry doors on Catalina take beating from salt air that mainland doors never see. Thresholds corrode, hinges bind, weatherstripping breaks down, and wood slabs swell with coastal humidity. We install Therma-Tru entry systems and marine-grade hardware on every Avalon door job we do. Read what’s involved on the Door Installation in Avalon page.

FAQs About Window Company in Avalon
We schedule Avalon visits around the ferry schedule, and the answer depends on current sailings and crew availability. When you call (903) 354-7134, a live person gives you a realistic window and confirms it in writing. There’s no charge for the estimate.
Many exterior window and door replacements in Avalon require review by the City’s building department, especially in older hillside homes where structural openings change. We coordinate permitting as part of the written quote and pull the permit before work starts. Your price reflects the permit before any work begins.
On a standard mainland window, yes. That’s why we specify marine-grade coatings and stainless hardware for Avalon rather than standard residential trim. It’s a modest upcharge that buys years of service life in an environment where ordinary aluminum fails in a few seasons. Call us for an exact quote; estimates are free.

What Avalon Customers Say
"Replaced eight drafty old windows that were basically single pane. The house is warmer already and the street noise is way down. Crew was on time both days and the price was exactly the quote."
- Harold Bemis"Our energy bill in summer was brutal. New windows made a real dent in it. Salesman wasn't pushy and didn't do the fake "today only" discount thing the others tried."
- Bethany Oh"Two bedroom windows that never opened and one that wouldn't stay up. All replaced in an afternoon. The crew was clean, hauled off the old frames, and the quote held."
- Colette Rhee
